Abstract
The immunological properties of a phage-resistant variant of Brucella abortus were examined. This variant, which was smooth and identical with the phage-susceptible parent strain in all cultural, biochemical and serological properties studied, was strongly antigenic in rabbits and guineapigs, inducing high titres of antibodies and delayed hypersensitivity to Br. abortus antigens. It was also fully virulent for mice and guinea-pigs.
